In addition to multiple moments of beyond adorable affection, the "Blank Space" singer and Calvin celebrated her winning with a smooch for the world to see.

The singer, who debuted her star-studded "Bad Blood" video on Sunday, was seated in a star-studded front row at the Las Vegas show with Ed Sheeran, Hailee Steinfeld, "Empire" actress Serayah and her brother Austin.

After winning the night's top artist prize, Taylor took a moment to honor others who were reaching a milestone.

"Oh, this is such a good night!" she said on stage. "Early this morning I watched my brother Austin graduate from Notre Dame [and] to anyone who's graduating this year, this is for you."
